APPARATUS FOR SOLDERING CANS.

SPECIFICATION forming part of Letters Patent No. 238,580, dated March 8, 1881. Application filed November 16, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. GILBER- sLEVE, a citizen of the United States, residing near Oamden, in the county of Kent and State of Delaware, have invented certain new and useful Improvements in Apparatus for Soldering Oans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth- [O ers skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has for its objects to provide an improved apparatus for soldering tin cans, whereby skilled labor may be dispensed with and the work accomplished by any person of ordinary skill and intelligence, thus placing it in the power of farmers and small packers to manufacture their own cans with great economy. These objects I attain by the mechanism illustrated in the accompanying drawings, in which Figurelrepresentsaperspective view, showing my improved apparatus complete. Fig. 2 represents a longitudinal vertical section thereof; Fig. 3, a transverse vertical sectional view; Fig. 4, a view detached, showingcertain of the soldering devices in detail; and Fig. 5, a detached perspective view of a removable door employed in connection with my improved apparatus.

The letter A indicates a rectangular casing of metal, constructed with internal longitudinal partitions, B, extending from the bottom upward into the casing, and terminating at about half-way from the top of said casing. The bottom of the casing between the parti- 0 tions B is provided with openings 0, through which the wick-tube of a lamp or a gas-burner may be inserted, in order to heat the apparatus. The casing is also provided with openings D E at opposite ends. Through the openings D the heat from a gas or other furnace may be introduced when found convenient, the products of combustion escaping throughopening E. i

The letters F G indicate two dampers, which lie in the positions indicated in Fig. 2, when the apparatus is to be employed for soldering the tops on the cans, and which may be elevated into a horizontal position when the apparatus is to be employed for heating soldering-irons to be used "in soldering the vertical seams in the cans, the heat in this instance passing below the dampers, as well as above the same.

The casing is mounted upon legs H, which are secured in any convenient manner, by means of screws I or otherwise.

On opposite sides the casing is provided with openings K contiguous to the respective dampers, the said openings having located in front of them the hearths L, which serve as a rest for the soldering-irons and other necessary tools, the irons being inserted through the openings K for the purpose of heating, the dampers during the operation being raised to a horizontal position. The openings K, when the apparatus is not in use for heating the irons, are closed by the doors L.

The top of the casing is formed or provided with a shallow trough or pan, M, to which is secured a flat cover or top, N. The said top or cover is provided, near each end, with openings O, for the introduction of solder, with which the pan is charged when the apparatus is in use, the solder being kept in a molten condition by the heat below. The said top is also provided with openings P P, through which the edge of the can to be soldered is inserted in the solder, as more fully hereinafter specified. At opposite edges ofthe openings P are formed ways R S, the ways R extending in a direction longitudinal to the top of the casing and the ways S transversely to the said top. In the ways It are located and adapted to slide the adjustable support-ingplates T, which are slotted longitudinally at 0 U and adjustably confined by set-screws V, so that they can be set to or from each other at any desired distance that may be required. The said plates are provided with grooves W at their outer corners, which serve to support the edge of the can while being soldered, and permit it to dip a sui'ficient distance into the molten solder contained in the trough or pan.

In the ways S are located theadjustable slotted plates X, which are confined by set-screws Y, so as to be adjustable back and forth. The said plates T form a support for the bottom of the can being soldered, and serve to hold it in place duringthe operation.

The letter A indicates two adjustable curved supports, secured, by means of set-screws B,to opposite sides of the casing A contiguous to the soldering-openings in the same. These supports A serve to support the cylindrical portion of the can in an inclined position, with its lower edge and the edge of the can-bottom resting in the grooves in the plates T, so as to dip into the solder in the pan or trough, the peculiar configuration of the said grooves and the curved supports permitting the can to be turned, so as to bring all parts of its lower edge and adjoining edge of the can-bottom successively into the solder, so as to thoroughly and effectually solder the joint from the outside.

The letter 0 indicates two sets of standards adjustably secured, by means of set-screws D, at the rear of the respective soldering-openings, to the top of the pan or trough. These standards are provided with bearings at their upper ends for the journals of the swinging plates E, which are provided with adjustable supports F, secured by setscrews G, the said supports serving to seize the lower part of the can to bring it to a vertical position, as more fully hereinafter set forth.

The operation of my invention will be readily understood in connection with the above description, and is as follows: When required to solder the bottoms to cans the parts are arranged in the position shown in Fig. 1. The pan is then filled with solder and heat is applied thereto. The cans, with the bottoms in place, and the joint prepared with a suitasuch as rosin, are then placed in the apparatus by an operative, the 'upper cylin drical part. of the can resting in the curved support, and the lower edge and edge of the bottom resting in the grooves in the plates T and against the plate X at opposite sides of the soldering-openin g. The can is then rotated by hand until the joint is completely covered with solder all around, when the can, by an upward movement, with its bottom resting against the swinging plate, is swung with said plate until the plate is in a horizontal position, with the can setting vertically thereon. This causes the solder to set uniformly around the edge of the can, preventing its accumulation in any one place and the absence of solder in other places, thus forming a perfect and secure joint.

It will be perceived that, by means of the apparatus as thus constructed, the whole operation of soldering the bottoms of the cans can be performed by the aid of mechanical guides, thus placing the work at the command of any person of ordinary capacity. Moreover, it will be seen that the cans are soldered from the outside, thus leaving the interior free from solder, which is objectionable, owing to the liability of the solder to corrode and injure the contents of the can.

In the present instance the apparatus is represented as constructed for use by two operatives simultaneously, who stand on opposite sides of the machine; but it is evident that it may be made smaller for use by a single operative, or larger for any number, the soldering devices in the last-mentioned case being arranged so that the operatives will stand alternately on opposite sides.

The apparatus is intended to be heated either by gas-jets or by the heated products of combustion from a suitable furnace. In the first case the jets are applied through the openings 0 G, the longitudinal partitions B forming a draft-flue, by means of which a steady flame is secured, the said flue operating somewhat after the manner of an ordinary lamp-chimney.

When the apparatus is to be used in connection with a furnace, nected, by means of a suitable pipe, with the opening D, the products of combustion passing longitudinally through the apparatus and out of the opening E.

When required to heat the soldering-irons, the dampers are elevated to a horizontal position, and when required to heat the pan they are dropped, as shown in Fig. 1.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-- I. In an apparatus for soldering cans, the rectangular casing provided with openings for the application of heat and of solderingtools, and with longitudinal partitions and dampers, whereby the heat may be utilized to melt the solder in a trough, or to heat soldering-tools inserted through the openings provided for the purpose, substantially as specified.

2. In combination with with the pan provided one or more openings in its cover for the edge of the can, the adjustable plates provided with grooves adapted to receive and support the edge of the can, substantially as specified.

3. In combination with the adjustable plates at the openings in the cover, the adjustable curved support for holding the cans in an inclined position, and permitting them to be rotated during soldering, substantially as specified.

at. In combination with the casing and the devices for applying solder to the cans, the swinging plates provided with adjustable supports, and adapted to receive the cans and support them in a vertical position, whereby the solder is uniformly distributed around the joint, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
